Green walls have witnessed increased popularity in recent times, so now they can be found all over the world, both indoors and outdoors, attached to existing walls freestanding or,in numerous shapes and sizes. But have you ever wondered why they are so popular? Here are some of the reasons.
When a building is exposed to solar radiation, it heats up. During warmer months, there is an increased demand for cooling systems, which leads to higher energy consumption. Recent studies have demonstrated that the surface of a green wall can be as much as 10°C cooler than the one of an exposed wall, meaning that notably less heat is radiated inward. Apart from reducing cooling requirements, green walls help mitigate the heat island effect and save energy during the summer months.
Through the process called transpiration, plants cool make their surrounding environment slightly cooler. As this increases with each additional plant, a green wall with many plants can reduce the room temperature by up to 7°C and cut the electricity bill by as much as 20%. During winter, this living wall system represents extra insulation owing to the fact that there is an additional layer of air between the greenery and the wall that reduces the quantity of heat escaping and cold air coming in.
Health & Wellness
Green walls provide both tangible and spiritual connection to nature which is definitely missing in the contemporary concrete jungle. If you have these structures in your workplace, some studies have demonstrated that simply having a view of greenery increases productivity. Moreover, having plants indoors alleviate the symptoms of discomfort, which consequently decreases the number of days off due to various illnesses.
Air quality is a tremendously important aspect of health and wellness and plants are proven to filter the air and remove toxins, in addition to providing energy-rich oxygen. It goes without saying that these benefits are multiplied with each additional plant, so a green wall with many different plants is likely to have a major positive impact.
From the aesthetic point of view, it is not an overstatement to say that green walls can be seen as strikingly beautiful, unique and original works of art created to best complement their surroundings. Utilizing this diversity of plants and incorporating different species plants become our paints and walls our canvases.
However, designing a green wall that is diverse, captivating, intriguing and a real pleasure to look at is by no means an easy task. It requires in-depth knowledge of various plant species, strategic planning, a strong sense of design and a whole heap of creativity. You can construct them in combination with eye-catching natural stones to further enhance their visual appeal. For instance, rustic stone wall cladding can be used as an ideal surface if you really want to make a statement with your green wall and create a gorgeous living masterpiece.
It is a well-known fact that the leaves of plants attenuate sounds by absorbing, reflecting and refracting acoustic energy in smaller amounts. What this practically means is that if more plants are present in a room, better noise reduction will be attained. As green walls commonly contain a number of plants, they can substantially improve the very acoustics of a room.
Plants are sometimes used in buildings for their acoustical benefit alone and they have been used for decades as barriers against urban noise pollution. A green wall built on the exterior of a building will do the same – it will insulate against noise and vibrations, as well as reduce sound penetration. Additionally, it can help absorb the echo which is bouncing off buildings, dampening the noise pollution in large cities even further.
